Detection system and method for authentication

Abstract

A detection system includes a portable object that comprises a sensor configured to detect biological information on a user and is portable by the user, and a function execution device configured to acquire the biological information on the user detected by the sensor through communication, and execute a predetermined function based on an authentication result of the user associated with the biological information on the user.

What is claimed is: 
     
         1 . A detection system comprising:
 a portable object that comprises a sensor configured to detect biological information on a user and is portable by the user; and   a function execution device configured to acquire the biological information on the user detected by the sensor through communication, and execute a predetermined function based on an authentication result of the user associated with the biological information on the user.   
     
     
         2 . The detection system according to  claim 1 , wherein the function execution device is configured to acquire the biological information on the user detected by the sensor, when triggered because the portable object has been brought into a predetermined state. 
     
     
         3 . The detection system according to  claim 2 , wherein the function execution device is configured to acquire the biological information on the user detected by the sensor, when triggered because the portable object and the function execution device are within a predetermined distance from each other. 
     
     
         4 . The detection system according to  claim 2 , wherein the function execution device is configured to acquire the biological information on the user detected by the sensor, when triggered because the user has performed an operation for executing the predetermined function to the portable object or the function execution device. 
     
     
         5 . The detection system according to  claim 2 , wherein the function execution device is configured to acquire the biological information on the user detected by the sensor, when triggered because the function execution device has read information on the portable object. 
     
     
         6 . The detection system according to  claim 1 , wherein the portable object is a smartphone, a tablet computer, a smart watch, or a card comprising a storage configured to store therein information. 
     
     
         7 . The detection system according to  claim 1 , wherein the sensor is configured to detect at least one of a vascular pattern of the user and a fingerprint of the user. 
     
     
         8 . The detection system according to  claim 7 , wherein the sensor comprises a semiconductor containing amorphous silicon and a semiconductor containing polysilicon, and is configured to detect the vascular pattern of the user and the fingerprint of the user. 
     
     
         9 . A method for authentication comprising:
 a biological information acquiring step of acquiring biological information on a user through communication from a sensor that is provided in a portable object portable by the user, and is configured to detect the biological information on the user; and   a function executing step of executing a predetermined function based on an authentication result of the user associated with the biological information on the user.
